5. The method for skipping title sequence of a multimedia file as claimed in claim 4 , wherein the step of matching the first portion feature data of the first multimedia with the second multimedia to obtain the portion in the second multimedia which is consistent with the first portion feature data of the first multimedia comprises: determining a matching duration, wherein the matching duration is less than a full-length of the second multimedia file; obtaining a file content to be matched of the second multimedia file in the matching duration; and matching the first portion feature data with the file content to be matched to obtain the portion in the second multimedia file which is consistent with the first portion feature data of the first multimedia file.

6. The method for skipping title sequence of a multimedia file as claimed in claim 5 , wherein a beginning time of the matching duration is substantially same as a beginning time of the second multimedia file.

7. An electronic device, comprising: a storage unit, used for storing a first multimedia file and a second multimedia file; and a processor, coupled to the storage unit for obtaining a first portion feature data of the first multimedia file, wherein the first multimedia file at least comprises a first portion, wherein the first portion feature data corresponds to a file content of the first portion of the first multimedia file, wherein the processor is further for obtaining a beginning time of a second portion of the second multimedia file according to the first portion feature data, wherein a file content of a first portion of the second multimedia file prior to the beginning time is consistent with the first portion feature data, wherein the processor is further for skipping the first portion of the second multimedia file prior to the beginning time of the second portion, and displaying the second portion of the second multimedia file when the second multimedia file is played, wherein a file content of the entire skipped portion of the second multimedia file is the same with the file content of the first portion of the first multimedia file.

8. The electronic device as claimed in claim 7 , wherein the processor is further for receiving a setting operation parameter and determining a beginning time of the first portion of the first multimedia file and an ending time of the first portion of the first multimedia file according to the setting operation parameter, wherein the processor is further for analyzing the first multimedia file regarding the beginning time of the first portion and the ending time of the first portion to obtain the first portion feature data of the first multimedia file.

9. The electronic device as claimed in claim 7 , wherein the first portion feature data comprises waveform of an audio signal and/or waveform of video signal of the first portion of the first multimedia file.

10. The electronic device as claimed in claim 7 , wherein the processor is further for matching the first portion feature data of the first multimedia file with the second multimedia file to obtain a portion in the second multimedia file which is consistent with the first portion feature data of the first multimedia file, wherein the processor is further for determining an ending time of the portion in the second multimedia file which is consistent with the first portion feature data of the first multimedia file as the beginning time of the second portion of the second multimedia file.

11. The electronic device as claimed in claim 10 , wherein the processor is further for determining a matching duration, and the matching duration is less than a full-length of the second multimedia file, wherein the processor is further for obtaining a file content to be matched of the second multimedia file in the matching duration, wherein the processor is further for matching the first portion feature data with the file content to be matched to obtain the portion in the second multimedia file which is consistent with the first portion feature data of the first multimedia file.

12. The electronic device as claimed in claim 11 , wherein a beginning time of the matching duration is substantially same as a beginning time of the second multimedia file.

13. An electronic device, comprising: a network unit, used for receiving a second multimedia file from a multimedia file sharing device via Internet; a storage unit, used for storing the second multimedia file; and a processor, coupled to the network unit and the storage unit for obtaining a beginning time of a second portion of the second multimedia file from the multimedia file sharing device through the network unit, wherein a file content of a first portion of the second multimedia file prior to the beginning time is consistent with a first portion feature data corresponding to a file content of a first portion of a first multimedia file, wherein the processor is further for skipping the first portion of the second multimedia file prior to the beginning time of the second portion of the second multimedia file, and displaying the second portion of the second multimedia file when the second multimedia file is played, wherein a file content of the entire skipped portion of the second multimedia file is the same with the file content of the first portion of the first multimedia file.

14. The electronic device as claimed in claim 13 , wherein the beginning time of the second portion of the second multimedia file is obtained by the multimedia file sharing device according to the first portion feature data of the first multimedia file, wherein the first portion feature data of the first multimedia file is obtained by the multimedia file sharing device through analyzing the first multimedia file regarding a beginning time of the first portion of the first multimedia file and an ending time of the first portion of the first multimedia file.

15. The electronic device as claimed in claim 13 , wherein the beginning time of the second portion of the second multimedia file is decided by the multimedia file sharing device according to an ending time of a portion in the second multimedia file which is consistent with the first portion feature data of the first multimedia file.
